Manufacture and assembly is simplified through this simplified one-piece structure of the oil pump cover.
Description
Technical field
The present invention relates to a kind of oil pump cover that is used for lubricating pump of automobile, by this oil pump cover can the closed car oil pump housing so that prevent to be arranged on the influence that pump mechanism in the housing is subjected to environment.
Background technique
For example disclose lubricating pump of automobile in a kind of oil sump that is arranged on internal-combustion engine by patent documentation DE 196 30 545 A1, this lubricating pump of automobile has oil pump cover.Be extruded with a tubulose protuberance from this oil pump cover, on this protuberance, be connected with suction passage by means of a plurality of bolt flanges.Suction passage is made up of the pipe of bending, and its suction inlet is that the inlet port of oil suction terminates in the oil suction basket, and this oil suction basket is arranged on the lower bottom part of oil sump.
The shortcoming of this oil pump cover is, make and assemble consuming time too much, thereby make the manufacturing costliness of internal-combustion engine.
Summary of the invention
Technical problem to be solved by this invention is that it is easy to create a kind of manufacturing, the easy-on oil pump cover.
The oil pump cover that is used for lubricating pump of automobile by the present invention has cover plate, can cover the part of lubricating pump of automobile by this cover plate.For example, cover plate can be connected with housing, is subjected to the influence of environment so that prevent pump mechanism.In addition, oil pump cover has inlet line, and it can be connected with the inside of lubricating pump of automobile, for example, is the pump mechanism fuel feeding of lubricating pump of automobile.According to the present invention, inlet line and cover plate design integratedly.Inlet line is like this design, and the lower bottom part that makes the inlet port that is used to aspirate oil plant close on oil sump under mounted state is arranged.
Thus, inlet line is designed to the parts with the cover plate one, and therefore, inlet line arrives the bottom of oil sump, and does not need inlet line is connected with the cover plate of oil pump cover as the parts that separate.The necessity that its flange that has saved inlet line connects makes assembling can carry out faster and more simply thus.When using this oil pump cover, the assembling of internal-combustion engine also can be carried out faster and more at an easy rate.In addition, because therefore integrality can avoid the mating face between inlet line and the cover plate, making does not need to be provided with seal ring, has improved production thus.Avoid using add ons, can obviously reduce the packing less situation of appearance.
Inlet line preferably shrinks from inlet port to cover plate.This contraction especially taper or oblique truncated cone shape ground is carried out.Because obtain the bigger cross section in cover plate zone that carries out the transition to the inside of lubricating pump of automobile than inlet line in the inlet port zone, so the oil that transition is pumped is lower in the flowing velocity in inlet port zone.Because flowing velocity is lower, has avoided the particle or the suspended matter of deposition rolled-up, thereby reduced to pump the danger of undesirable suspended matter.This makes can save filter or separator.
Cover plate can have attachment hole, for example can be by being bolted on the lubricating pump of automobile by this attachment hole cover plate.Cover plate especially can have a receiving bore, by this hole receivability and/or supporting pump shaft.Support by the fixed pump lid thus by its pump shaft that especially can drive the pump mechanism of lubricating pump of automobile.
Especially preferred is that oil pump cover can be by casting, especially high pressure die casting production.Especially when inlet line was designed to taper basically, inlet line can especially easily be made by a core when casting.This makes flat substantially cover plate just be equipped with especially long inlet line when moulding.The ratio of the Mean length of inlet line and the height of mounted cover plate is 1.0 to 5.0, preferably 1.5 to 3.0, especially preferably 1.5 to 2.0.
In addition, the invention still further relates to a kind of lubricating pump of automobile, can be the internal-combustion engine supply machine oil of automobile by this oil pump.This lubricating pump of automobile has a housing, and this housing can be by oil pump cover sealing, and this oil pump cover can design or construct as previously mentioned.Be provided with pump mechanism in lubricating pump of automobile inside, can pump oil by this pump mechanism.Inner pump mechanism is surrounded by housing and oil pump cover under the state of installing.Because oil pump cover does not need independent inlet line flange is connected on the described lubricating pump of automobile,, particularly be connected with the oil sump of internal-combustion engine as exclusive module so lubricating pump of automobile can be fast and made at an easy rate or assembling.
Especially constituted an oil sump that is used to hold machine oil by housing and/or cover plate, the pump impeller of pump mechanism can be through this machine oil motion.By this structure, pump impeller can be at two end face fuel feeding, and therefore in order to improve the power of pump, pump impeller can be provided for the chamber of transferring oil in both sides.
Especially preferred is that inlet line is connected with lubricating pump of automobile is inner in the darkest basically position by geodesy under mounted state.Because when lubricating pump of automobile quit work, suspended matter was got back in the oil sump by inlet line, be not retained in the housing, can avoid in lubricating pump of automobile, depositing suspended matter thus.
The invention still further relates to a kind of oil pan arrangement that is used for the oil sump of car combustion engine that has in addition.Oil pan arrangement has an oil pump cover, and this oil pump cover can design and/or expand as previously mentioned.Oil sump the darkest basically position on geodesy has lower bottom part, and the inlet port of inlet line is arranged on the position of closing on lower shoe.Therefore, the inlet line of oil pump cover extends to the darkest basically position of oil sump.The inlet port of inlet line and the spacing between the lower shoe can be between the 0.1cm to 5.0cm, especially between 0.2cm to 4.0cm, preferably between 0.3cm to 3.0cm, further preferably between 0.4cm to 2.0cm, especially preferably between 0.5cm to 1.0cm.
Description of drawings
The present invention is described in detail according to preferred form of implementation with reference to the accompanying drawings.
Among the figure:
Fig. 1 shows the schematic three-dimensional view according to oil pump cover of the present invention,
Fig. 2 shows the schematic cross sectional views of oil pump cover shown in Figure 1,
Fig. 3 shows the schematic three-dimensional view of the lubricating pump of automobile of part assembling, and
Fig. 4 shows the schematic sectional view of the oil pan arrangement that has lubricating pump of automobile shown in Figure 3.
Embodiment
In the lubricating pump of automobile 26 shown in the part, oil pump cover 10 is connected with the part of housing 20 in Fig. 3.Surround the inside of lubricating pump of automobile 26 jointly by the housing 20 and the cover plate 12 of oil pump cover, to hold pump mechanism.
In oil pan arrangement shown in Figure 4 28, lubricating pump of automobile 26 is connected from being inserted in the oil sump 30 and with described oil sump with oil pump cover 10.Oil sump 30 has lower bottom part 22 in its darkest position, and inlet line 14 extends to the lower bottom part zone, makes inlet port 22 and lower bottom part 32 only be provided with very little interval.
Constitute an oil sump 34 by oil pump cover 10 and housing 20, the impeller of pump mechanism can move and pass through or pass this oil sump 34.The ferry 24 excessively of inlet line 14 carries out the transition to the inside of lubricating pump of automobile 26 in the darkest position of lubricating pump of automobile 26, making does not have suspended matter and solid matter deposition 34 li of oil sumps.
